Assume that X follows a normal distribution N(25; 16).1)Sketch a graph in which you represent the graph of the density function of X, the line X = 25, and the probability P(20 < X < 30). 2)You are asked to evaluate the probability P(X ≥ 20). You are given the following answers:(a) 0.0034 (b) 0.4993 (c) 0.8944Without resorting to a complicated calculation, give the correct answer in your opinion, explainingyour choice.
